Hints for Reading Practice
1 Most of us can find 15 minutes or half an hour each day for some regular activity. For example, one famous surgeon always spent 15 minutes reading something before he went to sleep each day. Whether he went to bed at 10 p.m. or 2:30 a.m. made no difference.
2 "Speed Reading" courses teach students how to read more quickly. In such courses,teachers often ask students to find out how many words a minute he is reading. You can do this too: look at your watch every 5 or 10 minutes and write down the page number you have reached.
3 Obviously, you should not increase your reading speed if you do not understand what you are reading. If you find something you don&39;t understand in the book, or you cannot remember clearly the details of what is said, why not read the chapter again？
4 Take four or five pages of an interesting book you happen to be reading now. Read these pages as fast as you can. Don&39;t worry about whether you understand or not. If you keep doing this"lightning speed" reading for a period of time, you will usually find that your normal speed has increased.
5 Most paragraphs in an article have a topic sentence that expresses the central idea.
